T 0 all whom it may concern:

Be it known that I, EVA LUCRETIA TIL- LOTSON, of 76 and 7 8 High street,London, N. VV., England, shop assistant andsaleswoman, have invented newand useful Improvements in Sewing-MachineAttachments for Producing Tubesor Covering Cores; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming a part hereof.

This invention has reference to sewing machine attachments and has forits object to provide an improved device whereby a strip of fabric,leather or other material may be so stitched as to form a tube or rollin such manner that the raw edges and stitches will be concealed in theinterior thereof, said tube or roll being, if desired, filled with cord,twine, whale bone, wool or other material.

In order that my invention may be readily understood and carried intopractice, I will now proceed to describe the same fully with referenceto the accompanying drawings; in which Figure 1 is a plan view of thecomplete attachment. Fig. 2 is a collection of four views of the frame Ashown in Fig. 1, the central view showing said frame in the sameposition as in Fig. 1, the right hand view being taken from the right ofthe first mentioned view, the left hand view being taken from the leftof the first mentioned view, and the bottom view being taken from thefront of the first mentioned view. Fig. 3 is a collection of three viewsof the tube B and the arm rigid therewith, one of the views being a planin the same position as in Fig. 1, the right hand view being taken fromthe right of the first mentioned view and the lower view being takenfrom the front of the first mentioned view. Fig. 4 is a group of threeviews of the guide shield D shown in Fig. 1, one of the views being aplan in the same position as in Fig. 1, the view at the right beingtaken from the right of the first mentioned view, andthe view at thebottom being taken from the.

front of the first mentioned view. Fig. 5 is a hook or clutch forstarting the work through the tube. Fig. 6 is a sectional view on line6-6 of Fig. 1.

Throughout the separate views the same part is designated by the samereference character.

In Figs. 2, 3 and 4c the arrows indicate the direction in which the viewis taken. Referring more particularly to the drawings, A is a U-shapedframe two sides of which a and d are made thicker and heavier than thethird side Z), with the consequent formation of arecess as shown at cwhere the sides of different cross section are joined together. Atone'end of the frame, that is to say, at the free end of the part a, Iprovlde two recesses 0-0 so that the frame can be fixed to a presser barby the screw already in use for. fixing the sewing -machine foot or byan accessory'screw. It will be seen that the recesses 00 moreover, areformed in two short walls 39 and Q which are set at right angles to theplane of the side a of the frame and also at right angles to each other.

B is a tube, the use of which will be hereafter described, and at oneend of the tube 13 1s an arm 6 projecting at right angles thereto andfixed securely to the tube B. The arm 6 is of about the same thicknessas the arm I) of the frame A and it is intended in assembling theattachments that the arm e should be placed on top of the arm 5 andfastened thereto so that the part B will project across the open part ofthe U-frame A and the arm. 6 will fill the recess at the point 0. Inorder that the parts cand b shall be conveniently and firmly fastenedtogether I provide an aperture 1 in the part eand a correspondingaperture near the free end of the part b so that the two parts can besecurely screwed together by a small screw such as C which, when inplace, will be practically fiush'with the top face of the part 6.

When the parts B and A have been fastened together as just described,the part D is then thrust over the tube B until it reaches the positionindicated in Fig. 1. It will be seen that the member D is of sheet metaland comprises two parts 2 and 3 arranged at right angles to each other.It will be understood that the part 2 is somewhat elastic so as to fitclosely over the tube B and yet permit the insertion of the clothbetween itself and the tube. It will be seen, moreover, that the part 2is folded over as indicated at 4 so as to partly embrace the tube B onthe underside, the part 4. being entirely detached from the part 3 atits lower end. Moreover, the top part of the extension 2 is curvedinwardly as indicated 1 at 5 so as to partly embrace the member B whenthe whole device is assembled. The front end of the part 3 moreover, isturned downwardly as shown at 6 so that it may fit over the end of thearm 6 and the corner of the frame A formed by the parts Z) and d. Thepart D having been fitted over the part B in the manner just mentioned,D is se cured to the frame A by means of a screw E, the frame A havingan aperture 7 to receive said screw and the parts 6 and 3 being providedwith apertures 7 and 7 respectively, which register with the aperture 7when the parts are assembled in Fig. 1. Consequently, the screw E holdsthe part D to the frame and also passes down the front end of the partc.

The operation of the above described device is as follows :Theattachment being secured to the sewing machine as by the usual accessoryscrew, after having been assembled as in Fig. 1, one edge of a strip ofmaterial which it is desired to form into a roll or tube is passedbetween the part D and the tube B, the other edge being folded undernext to the cloth plate and being guided by the projection l, whichseparates I the under portion of the cloth from the cloth plate at theright when the parts are viewed as in Fig. 1. As the part D does notextend the entire length of the tube B the two edges of the cloth whichhave thus been wrapped around B may be alined toward the left end of thetube B. The presser-foot of the sew ing machine is then lowered onto thematerial in the usual way and the machine operated. It will be seen thatthe two edges of the material will be stitched together and suchstitching is continued until the tube of material thus formed projects ashort distance beyond the end j of the tube B. Up to this point it willbe seen that the edges 1 of the tube of material are on the outside.

the end K of the tube B and thrust entirely through the tube B andengaged with the material so that it is started into the interior of thetube B, the machine being of course worked at the same time. WVhen theroll of material is of suflicient length it will project from the end Kof the tube B so that it can be caught 'bythe hand and the hook orinstrument can then be discarded. It will be seen that in this way itcan conveniently make a roll or tube of material with the raw edgeslying within it and so concealed from view. Moreover, if so desired, thetube so made may be filled with any desired material such as cord, whalebone, wool or the like and this can be done while the outer tube isbeing made by inserting the filling material into the end of the tube B.

Having thus described my invention, I claim The combination with aU-shaped plate; of means at the extremity of one leg of the U adapted toattach said plate to a presser bar, the other leg of said U beingprovided with a screw receiving opening, a tubular member having a fiatextension projecting along the last mentioned leg of the U and providedwith an opening registering with the first mentioned opening, a guardplate having a lateral extension resting on said flat extension andprovided with an opening registering with said openings, said guardplate partly surrounding said tubular member for a portion of itslength, and a screw passing through the openings to hold said U-shapedplate, tubular member, and guard plate together and to secure the deviceto the cloth plate of a machine.

In witness whereof I aflix my signature in presence of two witnesses.
